Prodelight to Sponsor the Osaka Prefecture Events of the Inter-High School Championships (National High School Comprehensive Athletic Meet).

Prodelight Co., Ltd. (Chuo-ku, Osaka; President and CEO: Hidemitsu Konami, Securities Code: 5580, hereinafter 'Prodelight'), a company advancing telephone digital transformation (DX), announces its sponsorship of the Osaka Prefecture-hosted events of the Inter-High School Championships (Reiwa 8 National High School Comprehensive Athletic Meet, 'Kinki Sotai 2026'), to be held from Wednesday, July 22, 2026, to Friday, August 21, 2026.

The Inter-High School Championships (National High School Comprehensive Athletic Meet) is Japan's largest high school sports festival, organized by the Japan High School Physical Education Federation (established in 1948). Since the Niigata tournament in 1963, the events have been held as a unified competition, evolving into the largest sports event for high school students in terms of scale and significance. Through its summer and winter editions, the tournament has nurtured numerous young talents who go on to lead Japan's future sports landscape.

The 2026 tournament will be hosted primarily across two urban prefectures and four surrounding prefectures—Shiga, Kyoto, Osaka, Hyogo, Nara, and Wakayama—under the name 'Kinki Sotai 2026'.

Prodelight will support the event operations by providing its in-house developed cloud PBX system, 'INNOVERA', to the Osaka Prefectural Board of Education, the event organizer. As a company where employees actively engage in sports such as futsal and golf across departments and locations, Prodelight hopes to contribute to smooth communication during the tournament.

Through this sponsorship, the company will further its commitment to social contribution and next-generation development, in line with its corporate philosophy of 'Daily Challenge'—not only challenging itself but also becoming a company that empowers others to challenge.
